Electric charge within volcanic plumes on Earth and Io
… ground-level perturbations of the atmospheric electric potential gradient generated by particulate plumes were recorded. Simultaneous measurements, made at up to five sites around the volcano, are shown to be capable of detecting even very small quantities of volcanic particles, and tracking a …

Search for Magnetic Monopoles and Stable High-Electric-Charge Objects in 13 TeV Centre-of-Mass Energy Proton-Proton Collisions with the ATLAS Detector at the LHC
… monopole, despite the existence of isolated electric charges. The existence of such a particle with net magnetic charge not only restores the symmetry between electricity and magnetism but also provides an explanation for the quantization of electric charges due to a correlation between the …

On an Accelerated Fatigue -Testing Technique Using Piezoelectric Actuators
… phase transition alone did not result in ferroelectric fatigue. Rather, this fatigue is more likely due to electric charge accumulations at grain boundaries induced by repeated 180° domain switching.

A study of the pH-dependent charge of a selection of highly weathered humic soils
… said to result from the development of positive charge at low pH in soils with variable charge which is enhanced by the amphoteric behaviour of Fe and AI oxides as well as the presence of organic matter. Aluminium tends to form stable complexes with organic matter and also competes with lower …

Torsion Pendulum Testing of the LISA Charge Management System
… Most of such electrostatic forces scale with the electric charge deposited on the test masses. This problem is aggravated by the fact that isolated objects in space, such as the floating LISA test masses, accumulate electric charge due to the constant bombardment of cosmic rays and solar energetic …

ΑΛΛΗΛΕΠΙΔΡΑΣΕΙΣ ΙΟΝΤΩΝ ΚΑΙ ΠΡΟΣΑΝΑΤΟΛΙΣΜΕΝΩΝ ΘΥΛΑΚΟΕΙΔΩΝ ΚΥΑΝΟΒΑΚΤΗΡΙΩΝ
… AND NEUTRALIZATION OF THE STATIC NEGATIVE ELECTRIC CHARGE AT THE CYTOPLASMIC SURFACE OF THE THYLAKOIDS, AS WELL AS VIA CHAOTROPIC MODIFICATION OF SURFACE ELEMENTS, AT CONDITIONS PROVIDING FOR SUFFICIENT LOCAL ACCUMULATION OF CHAOTROPIC ANIONS. IN ADDITION, OUR RESULTS INDICATE THAT …

Studies of the inclusive semileptonic decays of the b-hadrons
… a new analysis, in which the correlation of the electric charge of the b-quark to that of the lepton is utilized to isolate different decay modes of the b-hadrons, is presented. Using the data collected by the DELPHI detector during the 1994 and 1995 data-taking periods, the inclusive b-hadron …

Visualization of water/oil displacement in porous media in the presence of chemical reaction.
… wettability condition, high pH value, and the electric charge density at the interface can improve the oil recovery percentage appreciably. However, the addition of sodium hydroxide changes the interfacial tension to an ultra-low value. Interfacial tension decreases as a result of the …

Evaluating the Electrical Response of Polyaniline to Mechanical Strain
This thesis focuses on the electrical output of polyaniline films subjected to uniaxial strain in hydrochloric acid solutions. Polyaniline belongs to novel class of materials known as conducting polymers. Alternating single and double bonds in the backbone of conducting polymers allow them to …

Development of a micro-FID using a diffusion flame
… to gauge sensitivity of the device, collected electric charge per mole (C/mol) was calculated and taken as a reference value of ionization efficiency. The result was 1.959x10-2 C/mol for methane which was about 34 times higher compared to the result obtained using a counter-flow flame, which …

Charge transport and breakdown physics in liquid/solid insulation systems
Liquid dielectrics provide superior electrical breakdown strength and heat transfer capability, especially when used in combination with liquid-immersed solid dielectrics. Over the past half-century, there has been extensive research characterizing "streamers" in order to prevent them, as they are …

Compact, Self-Cleaning Wet Electrostatic Precipitators
… particles, we use a process called corona discharge, which gives particles an electric charge and pulls them toward the wires. A small stream of water flows down the wires, washing the particles into a container below—making the system self-cleaning. We tested how different design choices …

Implementation of Microwave Transmissions for Rocket Exhaust Plume Diagnostics
… of the rocket. A conductor in the presence of an electric field (e.g. near the electric charge stored within a cloud) can channel an electric discharge. The electrical conductivity of the exhaust plume is related to its concentration of free electrons. The risk of a lightning strike in-flight is a …

DNA Chemical Reaction Network Design Synthesis and Compilation
… and requirements than computing just with electric charge. These challenges have led to ad-hoc design and programming methods with high development costs and limited device performance. At the present time, device building entails complete low-level detail immersion. We address these …

Plug-in Hybrid Electric Vehicle Supervisory Control Strategy Considerations for Engine Exhaust Emissions and Fuel Use
Defining key parameters for a charge sustaining supervisory (torque split) control strategy as well as an engine and catalyst warm-up strategy for a Split Parallel Architecture Extended-Range Electric Vehicle (SPA E-REV) is accomplished through empirically and experimentally measuring vehicle …
